1970 Dart First Restoration. Help Appreciated!

Your cowl area looks just like mine did in my 70 Dart. To fix mine I had bought a parts car for the cowl panel as well as other items. In my case I don't have any body or welding skills so i paid for a body shop to replace the complete panel. Once the shop got the old panel out found out that my rust problems went a little deeper. The vent area was rusted as well. The body shop fixed that part and welded on the replacement panel.
